Sure, I understand. Here is what I have done so far:
The pressure at the bottom of a cylinder is equal to the force at the bottom divided by the Area, or
[P(bottom) = P(atmosphere) + density*gravity*height.
because we are dealing with water and mercury, do I need to equate this formula...
A cylindrical container 1.2 m tall contains mercury to a certain depth, d. The rest of the cylinder is filled with water. If the pressure at the bottom of the cylinder is 1.9 atm, what is the depth d?
Does anyone have any ideas on how to approach this problem, better yet,solve it!?
